Merge branch 'intel-wired-lan-driver-updates-2024-06-03'

Jacob Keller says:

====================
Intel Wired LAN Driver Updates 2024-06-03

This series includes miscellaneous improvements for the ice as well as a
cleanup to the Makefiles for all Intel net drivers.

Andy fixes all of the Intel net driver Makefiles to use the documented
'*-y' syntax for specifying object files to link into kernel driver
modules, rather than the '*-objs' syntax which works but is documented as
reserved for user-space host programs.

Jacob has a cleanup to refactor rounding logic in the ice driver into a
common roundup_u64 helper function.

Michal Schmidt replaces irq_set_affinity_hint() to use
irq_update_affinity_hint() which behaves better with user-applied affinity
settings.
